Application filed March 19, 1888. Serial No. 267,782. (Model.)

f-citizen ot the Dominion of Canada, residing at Chicago, in the county of ACook and State of Illinois, have invent-ed certain new and useful Improvements in Check-Protectors, of which the following is a specification, to wit: My invent-ion relates to improvements in check-protectors; and it consists in the construction, arrangement, and operation of the parts, as will be hereinafter -fully described, and particularly pointed out in the claims. 1 To enable others skilled in the art to which my invention relates to make and usev the same, I-will now proceed to describe my iinproveinent, referring to the accompanying g hase A. On this shaft at the top is a crank drawings, in whichn Figure 1 is a plan view. Fig. i. is a central longitudinal section. section on :l: on ofFig. 1. Fig. i is a transverse section onq/ y otlFig. l. Fig. 5 is an under plan View. Fig. 6 is a back view showing a modication of the'stop p. Figs. 7 and .niatcriah preferably of cast-iron.

8 are views showing -a modification of the block operating the punch-head, and Figs. 9 and 10 are views of another modification of the same device. Fig. l1 is a detail View of the block (t5. Fig. 12,L Sheetf, is an enlarged view ofthe ratchet-wheels h-'and b3, showing one wheel broken away'and the other behind it and showing the teeth of each inclined in the `opposite direction. Figli? is a vertical sectional view of the removable punches, showingl connection with shank and special construction. Fig. 14 isa plan View showing rod fa, springen, and shaft H, and theirrelat-ive location and arrangement. Fig. 15y is a view showing the form of irregular plate al. Fig. 1G is a detail view of the spring-catch, showing the lip bs. Fig. 17 is an enlarged view of the ratchet-wheels, with one out away, showing the irregular plate in position; and Fig. 18 is a detail sectional yview of the knob of the crank-handle 'and its ii flicating-pin.

Similar letters refer to like parts throughont the several views. 4

A is the base or table, made of any suitable Upon this base is mounted a shell or casing, B, containing most of the working parts el my machine,

made in any suitable form, but preterabl y oi Fig. 3 is a transverse the shape shown in the drawings. It is removably secured to the hase by screws c e,

running into the body of the shell through` the base from the bottom. C is a dial-plate, removably attached by screws to the top of the shell B, and having `on its face at proper intervals the figures 1, 2,

3, 4,- 5, G, 7, 8, D, and 0, the dollar-sign, and asteriskQand having holes c c opposite each figure andsign; or there may be any other figures or signs, as ina-y bel found necessary. I preferably form the inside surface of the dialplate with a flange to hold it concentric with the shell, so that it will beheld iirin. Through the center of the plate "C passes a vertical shaft, o., journaled in said plate and in .the

handle or lever, I), to revolve the shaft, this collar, so that the pin will drop or be forced into the holes c c, and maybe Withdrawn by raising upon theknob in the act of changing the position of the lever.

The shell Il on the inside has at one point a groove, f, running down preferably to a point on a line with the top of the doubleiianged cylinder E. In this groove `fits atenf cned block, g, which is riveted to athin. piece of spring-steel, 77 whose end 'rests loosely on a shoulder, Iz, on the cylinder E, and held in position by a clcrewnut, k, which screws oitothe shaft a on top of the huh, andabove this nut is a set-collar, I. on the shat't to hold the parts in position. The steel piece 7L is ot snliicicnt strength to carry and return the block immediately upon bein released a sinficient heightto clear the punch-shanks.

Across the inside of the'shcll B near its top runs a horizontal shaft, lI, jonrnaled in both sides of the shell. On the end ot thcshatt on the outside ol the shell is a crank-handle, I, for oscillating the shaft. On the inside, rigtop of the hub F of the 4 idly secured to the shaft il, is a doe', ii, over the block g, 'the doi,r i( being made in such forni that when the Shaft is oseillated the dog will press down on the block y, So as to force down the punches under the hloek in a Straight line, and thereby avoid the tearing;` of the cheek or paper while being pui'iched or perforated.

The object of using' the hlocliV y is fo prevent the punclreylincler i'rom moving while vthe performing ie being done, which, il it did oeeur, 'the check or paper, lining.;` held .firmly between the vfeed-rolls, would eause the peri lind from experience that when 'the dog is; operated in coniaclwit'h the punehshanl; wilhoutthe intervention ol. the hloclc the eiiccl. is tomove the puuch-cylinder a linie, this heingenoug'h to make the pml'orationesI rough and 'unseemly and the check or paper liable to tear, the arc that the doe' moves in heine; sul'licient lo cause thie` -tro'ulfiie, and i find that hy using the block g between the dog' and the puncli-shank, and eoniacliney with both, a direct and positive dowi'iivard slraighl movement oi the punch is insui.` i and this dilliouliy overcome.

ihe Shaft il' hals` on ita Spring, in, Secured at one end to the shalt and running' and resting upon and hooked over a rod,-n., which runs through the shell near the top. lfhis Spring' returns the shaft ll to its nornial position, Carrying up with it the dog, allowing the block to he forced up and outol the way of the punehshank. This spring;` has also the further duty to do-that is, the feeding. The ui'iward momentum given to the shaft ll hy the springnl and the oprinej in ihe punchshank is checked hy 'the doel Striking agrainsr` the un-ler eide oli' the dial plate, which wil relieve the ,strain from the retaining-pawi ol the feed mechanism which would otherwise occur, and t'llereoy enables me to use a weak leainingpa-Wl, securing,r less friction and noise and heller ,l'reedom for the parisl to Work.

In order to prevent the shalt il .l'rom moving too far down in itsI do\vn\\'ard movement, and through the dog and block from forcing the punches too far down against the stripper-plate, and thereby injuring` the parts, i provide on the eiank-l1amlle l a lugr or projection., o, (if-appropriate length, which strikes against a projection or l rachelp, on the shell and limits the downward movement of the shaft and dog, and also prevents the pawl of the feed mechanism from engaging' more than one tooth at a time inthe ratchet, au presently explained.

Below` the punch-cylinder and stripperplate isa die-plate, L, which encirclcs lhe bottom of the shaft ct and is lixed to revolve with said shaft, heilig heid ny lmeans ol' the collar or plate q, which is rigidly secured to the shaft, a screw passing through the eollar 1 into the die-plate. Un the lower l'acc ol' the die-plate are duplicate figures and signsas onthe dial-plaie; hut their poeitions are in oppoSiiion to those ouille dial-plalie4those on the dial-plate being from lelt to right and. on the die-plate heilig;` from right; to lett, or vice versa. These figures and signsareformed in the die-plaie hy a seriesl oi' perferations for the passagfeoli the punches. might be made soli .iignsor figures or otherwise, as desired.

'lhrough the die-plate l', are small holeS yr near dieshafu direct ly under similar holes,.s, in the slripper-plate, through which holes in both plates pass dowel-pi ns, which are secured to the bottom face oi the lower huh oi the punch-cylinder.

yl`he stripper-plate .N is-'direetly over the They, however,

die-plate, with a Space. between sui'iieient to ad mittheinseriion or wiihdrawai ol the cheek or paper to he perforated. lihis plate surroundsthe shaft u. and revolves with it. This stri iper-plate has through it and directly over it the same perform-ions of Signe and 'figures,` as in the die-plate. ihese holes or perforations acl; as a gu ide i'or the punches and also to allow the punches io pass` up without carrying` the paper or check up wirh it or them. The doucl-pinfs before mentioned malt'e both plates revolve with the Shaft', als is evident.

'I is a double-flanged cylinder or punchdink havingr a l'op huh and bottoni huh, F F, and a .solid hody having; a luroove, i", in its periphery, which l'orms top and lower flanges,

i) l) are the punoh shuulis or rods, which .paeslhroug'h holes in the flanges oi' the punchcylinder and corresll'lond in numoer with the i'igures and signe in the die-plate. The top of these shanks or rods in their normal position extend sul'liciently ahove the llanges lo he in proximity to the preeeingg-hlock g, operateifl by the dog h', so as to he readily pressed down when the shalt is oscillated. The lowerends oi' the puneh-shanli's are shouldered below the bottom flange, on which shoulder is riveted a small collar or disk, af. Between the flanges and eurroumliueT each punclrshank iS'a spiral sp1-iugm@ which reste against the top surface ol' the iower Mange, the spring' at the iop having ahearing against asmall u'af-iixeufi?, which is preferably loose on the puneh shank vslightly below the under surface of the topflange, and held down hy a pin, o3, passing` through the punch-slmnk and extending out a short distance beyond the periphery of the' washer (L2, i'or a purpose presently explained.

The object ol." this spring is to draw the punehee` out of rthe paper4 and return the punches and.punchehanks to their normal position when the pressure 'is relieved.

R ie what l call a punch hloelc or dish,"

made, preferahly,of brass orany other suitable material. In this block are holes corresponding with the figures or signs below. Through these holes are inserted the punches a4 a4, which perforate the paper, the construetion, arrangement, and connection of the punches with the punch-shanks being clearly shown in FigjlB ofthe drawings. The punchdisk R consists of a collar, which is riveted to the pu'iich-'shank P, forming one body, and

all together maybe called a punchf from which construction the office of the punchshankis evident, and which construction I prefer. The block is secured by screws or otherwise to the collar the screws passing into the block from above, so that the punches can be removed for repairs and for convenience in manufacture. `These punches are preferably headed, so that they will not be drawn out of the bloclqin ease the punch should stick in the die-plateor paper below, and they are also prevented from being pushed or forced upward by fitting vclosely against collar S is a block, preferably of an angle shape. It is fastened to the shell and passes through, extending beyond the inside wall of the same,

' at such aV point so as to be opposite the punch that is to be operated. This block is provided with a recess or slot, a5, to receive the pin d3 of the punch shank or rod, the block being placed at such a distance below the pin a3 that when the punches are in their normalpositionthe pin a3 will pass over the block in the revolution of the punch-disk; but when the punch is down the pin d will rest iuclosed in the slot a5 and prevent the operator from revolving the punch -disk should the punch by any means stiel: in the die-plate or paper below, thereby preventingr the check or paper from being torn, which would otherwise'oceur if the cylinder could be revolved, the paper being held between the feed-rollers. So long asthe pin rests in the slot, the punch-disk' cannot be revolved and no dama'geean be done to the cheek or to thev several parts of the machine. The jarring of the handle will, in most instances,

relieve the punch should it stick; but if thatv be not sufficient, relief can be given by inserting an instrument b( Anveen the stripperplate and the punch-block It, an aperture, a, being left in the shell for that purpose.

u? is an arm removably attached to the shaft Il', near one end, the outer end of the arm being hinged to a connectirig-rod, a8, which passes downward and is connected to an irregularly-shaped plate, c, journaled upon the feed-shaft T, which runs through the base, the shaft being journaled in a boxing near one end of the baseat one end and` at the other being journaled in a lever, X, whose 'purpose will be presently explained. -The plate ai has attached at one end a sinallpawl, h', which engages the ratchet-wheel bl on the 'feed-shaft T on. one side of plate a9.' On 'the other side ot' plate 0.9 is another l ratchetwheel, U, slso on the shaft T. Both of said ratchet-wheels are removably yetv rigidly attached tosaid shaft, the plate a being held in position laterally by the ratchet-Wheels. The Jratchet-wheels b2 and b3 have their teeth inclined in opposite directions, one from the other, as shown in Figs. l2 and. 17 of the drawings, the opposite inclination of theteeth being l'or the purpose of holding the feed-roll lixed by means of the spring-catches b5 and Zr' while the paper or cheek is being perforated. lf it were not for this arrangement, the friction of the pawl b upon theratchetwheel h2 would cause the feed-roll to move while the punch is in the paper, thereby malting the perforations rough. The object ot' wheel lisis to hold the feed-roll` from going too far when the feeding is being done, and is accomplished by means of the spring-catch 57 dropping into the teeth, the projection b9 on plate-df having passed upward so as to permit this, thus making the spaces between the figures or sizes uniform and equal.

-if is a post or proj eetion from the base on one side of the shaft, to which is removably secured a small (preferably spring) pawl, b5, which en gages the ratchet-wheel b2 to prevent the feed-wheel 'from being-'moved backward when the pawl. Zr' is going downward 'to engage another tooth. the shaft is another post or projection, h6, on which is removably secured a pawl, bi, preferably oi' spring-steel, whose end engages the from being moved too far when the feedingis done. The object of the lip or projection bS on said pawlis, that when it is engaged by the projection U) on the plate a9 in its downward or backward movement, to disen gage the end of said pawl b? from the ratchet-tooth in wheel vZi and to hold the pawl out of contact with said tooth of said wheel h3 untilthe pawl b has engaged a tooth in the ratchet-wheel b2, and in the upward 0r forward movement of the arm @Thas revolved the ratchet-Wheel b3 and the feed-rt ll far enough for the'point of the tooth in said wheel b3 to have passed under the end of pawl ZF. The projection b9, on plate a is so formed as to allow the point of pawl bi to drop into the next tooth, thus se'4 cui-ely locking the feed-wheel in one direction, and the pawl b5 is so arranged as to have dropped into a tooth in wheel b2, vthus securely lookin g the feed-wheel in the other direction, the objects of this construction and arrangement being to hold the paper iirmly` and immovable while the perforating or punching is being done, and also `to prevent overspacing should the operator allow the operating crank; handle to go upwardly too rapidly, or if it should slip from his hand and ily up. This will prevent irregular spacing. lf it were notfor this, and irregular spacing occurred, there would bc a possibility of in- On the opposite side of Y IIO einer 5 (i in a cheek-protector, the Combination, with the feed-rolls, oftwo. ret-chetfwheele mounted to rotate together and having teeth ei'we i the relie, es; 'for tin'ongh ile eilt 3.. to one nmeiiine es 'to piene the ylino on Wiiioh the In i di" ,se n nneixed under the .i "g, of the indi ingv oppositeiy arranged, fr plate provided with a. 5' nreeitet :1l premere leihen projection and carrying ,am operating-pewi reiee i from. n z nine-plee@ oi' the iever, en raging-with one of the Said Whe-ele, and a,
